Joomla CSS sIFR cross browser problems

which usually works on my other joomla sites fine but if i turn it on the contentheading it pushes the page down in IE6 and IE7 but looks fine in Fire Fox it is not turned on now but when it is it pushed all the content down just below the left nav . [login to view URL];Itemid=1 (i edit what gets sIFR by editing the code at the bottom of [login to view URL] the mambot of course is published) <script type="text/javascript"> if(typeof sIFR == "function"){ [login to view URL](".contentheading1,.module h3, .contentheading2, .componentheading-,.title, h3", named( {sFlashSrc: "mambots/system/P22ACHUN.swf", sColor: "#3b2314", sWmode: "transparent"} )); } </script> when sIFR is turned on it looks ok here [login to view URL];flypage=flypage-butts.tpl&product_id=23&category_id=6&option=com_virtuemart&Itemid=61 alos page ending here, as you can see it doesn't go all the way down. [login to view URL];option=com_virtuemart&Itemid=61 this is my fault as i butchered the template
